Abstract
GdX (also named Ubl4A) is a house‐keeping gene located on the X chromosome and encodes a protein harboring an ubiquitin‐like domain in human and mouse. Although identified in 1988, the function of GdX remains unknown. To elucidate the role of GdX in vivo, we generated a conditional GdX knockout mouse in which Exon 2 was flanked by two loxP sites. We obtained viable and fertile mice with homozygous GdXflox/flox or GdXflox/Y allele. Germ‐line transmission was confirmed by crossing the mouse bearing conditionally targeted allele with an EIIα‐Cre transgenic mouse. GdX was successfully depleted in tissues of EIIα‐Cre‐GdX‐null mice. GdX−/− and GdX−/Y mice are viable and exhibit normal development compared with wild‐type littermates within 6 months during our observation. We also observed that GdX knockout male mice were functionally normal in the reproductive system where Ubl4B was specifically expressed. GdXflox/flox and GdXflox/Y conditional mice provide a tool for further tissue‐specific function analysis of the GdX protein under different conditions. genesis 00:1–9, 2012. © 2012 Wiley Periodicals, Inc.
